It's kind of sad to hear of parents treating their own off-spring this way. However, let's face it: Some mothers - and, okay, some fathers too - are hard-faced so-and-so's regardless of the presence or absence of a religious faith.
But I suppose if a mother is this way anyway, the stifling judgementalism of the JW influence would give her that extra off-putting edge. Is there a scripture anywhere on this kind of parental behaviour?
